This tutorial discusses how jumbo frames may affect website performance
Do you find that your ip address occasionally gets banned by web servers? Or maybe you experience your browser hanging when viewing particular websites. These could be caused by certain settings in your network card’s configuration.
Some network cards have a function called “Jumbo Frames” which is often enabled by default. We have experienced, and seen others referring to, this setting as a possible cause of connectivity issues. If you are experiencing the issues previously mentioned, you could try disabling this setting in your network card to see if that alleviates the problem.
For more detailed information regarding your specific network card, including instructions on adjusting this setting, you will need to consult your hardware manufacturer.
